The club's under-fire owners Fenway Sports Group have now decided to revisit the plans, according to The Times.

Senior Anfield officials have not yet decided to revise the ticket structure, but discussions are apparently set to continue this week including chief executive Ian Ayre.

Ayre came in for criticism for defending the price hike, pointing to tickets in other areas of the ground which had either stayed at the same price or fallen.

FSG are said to be surprised by the extent of the protest on Merseyside, triggering the response.

The walk-out was organised by fans' group Spirit of Shankly, and their chair Jay McKenna warned that it was only the beginning.

“For us, it is unequivocal: this is the start,” he said. “We don’t have a firm idea of what we will do yet as this has all happened very quickly, so we will take the next two days to take stock and talk to the supporters about what we do next.
